One, too many verticillas
Rotation of 4 to 5 branches at the base results in the neck pinching of the tree, which results in the faintness of the center of the tree and affects the growth potential of the tree. The solution: remove one of the lower branches from the whorled branches, one retracts, and then pull down the other two or three branches.
Second, it is too high
The height of the apple tree is more than 120 centimeters. The lower part of the trunk is bald, and the growth of the tree is relatively weak. The molding is late, which is not conducive to early high yield. Solution: Carve buds on the appropriate part of the trunk, or connect the abdomen in the appropriate area.
Third, the dryness is too low
The height of the apple tree is lower than 60 cm. The trunk is large and strong in the lower part of the trunk. However, the low position of the new shoot grows very long. The center of the tree is not clear and the quality of the sticking branch is poor, which affects the formation of the canopy. Solution: Shorten the upper branch of the tree to increase the amount of branches; gird the lower branch and remove the result year after year to enhance the growth potential of the upper part of the fruit tree.
Four, trim too heavy
As the tree is disordered, after pruning, most of the unused branches are removed, resulting in excessive pruning. The main branches on the trunk are scarred, the tree vigor is weak, and the growth of the leader branches is also weak, which affects the growth potential of the tree. The solution: on the trunk of the useless branch, can be part of the appropriate removal, re-contracted part, with the "three saw" to press down part of the main branch on the back, no space to remove, there is room for Trimming flattened.
Five, spindle-shaped tree, too many branches
Some fruit growers in the production of spindle-shaped tree body are flattened in addition to the thinning of the tree. The useless branches are removed and the remaining part is fully flattened, resulting in twigs growing on the back and extending branches slowly. This affects the expansion of the crown. This method is incorrect. of. Solution: The length of the elongated branch in the lower part of the tree is more than 100 cm, and the length of the upper branch is 50-60 cm. For each part of the branch, the length of the branch is pulled; the length of the branch is not full. The buds are short-cut, but they can be allowed to continue to extend.
Six, pay attention to winter cut, light summer scissors
In winter, there are many branches and branches, and the amount of pruning is large. After entering the growing season, there are many sprouts near the cut, and the branches on the back are long and the branches do not keep up. This will cause winter cuts and cuts, summers, and winters. The vicious circle of the Qing dynasty is not only wasting a lot of nutrients in the tree, but also delaying the results. The quality of the fruit is poor and affects economic efficiency. Solution: When Wangshudong cuts, the interception should be moderate. Carving buds were carried out on the branches before budding; in the middle and late April, the useless shoots at the trimmings were promptly wiped; in late May, intensive gibbism was performed on the more prosperous branches; in July and August, the branches were softened to adjust the angle; For small angles, the backbone branches open at the base, sparse upright branches, leggy branches and competing branches.
